Belajar Bahasa Pemrograman Arduino dengan WOKWI Simulasi Traffic Light Lampu Lalu Lintas

Introduction

In this tutorial, you will learn how to create a basic traffic light simulation using Arduino programming with the WOKWI online simulator. This project is ideal for beginners looking to get hands-on experience with Arduino and understand how traffic lights function in a real-world scenario.

Step 1: Access the WOKWI Simulator

• Open your web browser and navigate to the WOKWI website: WOKWI.
• Create a free account if you don’t have one, or log in to your existing account.

Step 2: Set Up the Project

• Once logged in, start a new project by selecting "New Project".
• Search for "Arduino Uno" in the components library and add it to your project workspace.

Step 3: Wiring the Components

• Connect the LED lights to the Arduino Uno as follows:
  • Red LED: Connect the long leg (anode) to pin 13 and the short leg (cathode) to GND.
  • Yellow LED: Connect the long leg to pin 12 and the short leg to GND.
  • Green LED: Connect the long leg to pin 11 and the short leg to GND.
• Use a breadboard if necessary to help with the connections.

Step 4: Write the Arduino Program

• Click on the code editor and input the following code to control the traffic lights:

int redLight = 13;
int yellowLight = 12;
int greenLight = 11;

void setup() {
  pinMode(redLight, OUTPUT);
  pinMode(yellowLight, OUTPUT);
  pinMode(greenLight, OUTPUT);
}

void loop() {
  digitalWrite(redLight, HIGH);
  delay(5000); // Red light for 5 seconds
  digitalWrite(redLight, LOW);
  
  digitalWrite(greenLight, HIGH);
  delay(5000); // Green light for 5 seconds
  digitalWrite(greenLight, LOW);
  
  digitalWrite(yellowLight, HIGH);
  delay(2000); // Yellow light for 2 seconds
  digitalWrite(yellowLight, LOW);
}

• This code sets up three LEDs to simulate a traffic light, with specific delays for each color.

Step 5: Run the Simulation

• Click on the "Run" button in the WOKWI simulator to test your traffic light program.
• Observe the LEDs changing according to the logic defined in the code.

Step 6: Enhance the Program

• To add more functionality, you can modify the timing or integrate additional features, such as pedestrian signals or emergency vehicle overrides.

Conclusion

Congratulations! You have successfully created a basic traffic light simulation using Arduino in the WOKWI simulator. This project serves as a foundation for understanding more complex Arduino applications. Consider exploring other projects or enhancing this one with additional features. Happy coding!
